And putting with a midrange may be working for the time being, but after enough long comebacks due to glide-bys, you'll want to add a stable putter to your bag.

I concur. What he said

You need to bridge the gap between overstable driver and your mid. You need a neutral stability driver of choice like the examples Brad listed.
I'm not real familiar with the Pro Shark or your putting style but a traditional type putter like an aviar, challenger, omega, wizard, x puttr may allow you to run putts and minimize the distance of comebacks.

Personally I don't care for Champion plastic, especially for discs you need accuracy and control. If you don't like the way DX beats in I'd suggest Star plastic, as it is more durable than DX but has less low speed fade, better feel and I believe more controllable. I picked up a Star Roadrunner recently and I really like it, if you want greater high speed stability than I imagine a Star Teebird should serve you well.

I get grip-lock with Star plastic a lot.

It feels like a driver to me. 90% of my drives (with drivers) are with a Star Teebird. It's good to about 385' with a slight hyzer finish.
Champ Teebirds start off and stay more stable for longer than Star.

A Shark can obviously be thrown off the tee, but it depends on what kind of line you need/want to throw. A driver can be thrown on a lot lower lines and still maintain it's speed. If you try to throw a Shark on a 8' line drive, it is likely to not end up well.
